Fiber optic patch cable connector types

There are many types of fiber optic patch cables, that based on the types of the fiber optic connectors. Types including SC, LC, ST, FC, MU, MTRJ, E2000, SMA, MTP/MPO, etc. There are UPC and APC type fiber optic connectors; they are with different polished ferrules inside the connectors. For each fiber patch cord, all connectors should be either single mode type or multimode type, to use accordingly with the optical fiber type as in the cable.

There can be single mode UPC and single mode APC connectors on the same SMF patch cord, but for multimode, there is only UPC type connectors and thus only multimode UPC fiber patch cords. Based on the cable structure, there is simplex fiber patch cable, which only has one strand of optical fiber inside the single jacket. Duplex fiber patch cable can be regarded as two simplex types joint side by side. Multi fiber patch cables have many optical fibers inside the single cable jacket.
